Title: Process for preparing phosphatic fertilizing materials
IPC: C05B1/02
Filed: 1930-04-07
Abstract: A process of preparing phosphatic fertilizers comprises passing a stream of acid towards a receiving zone, intermixing said stream with a stream of finely divided phosphatic material and allowing the acid and phosphate to react under pressure in the said zone.  Acid from a tank 1, heated by steam coil 2, is fed via measuring device 6 to acid charging tank 9, and thence under pressure to a mixing valve 25, where it is mixed with ground phosphate rock.  This is conveyed thereto from a hopper 12 via measuring device 15, pump 18 and dust-charging hopper 21, and on its passage is aerated by jets 14, 19, 23.  In the mixing valve 25, the stream of dust is enclosed by a stream of acid, and thorough mixing occurs.  The mixture passes via control gate valve 26 on to a baffle 28 in a jacketed rotating autoclave 27, attached to which is a condenser 32, and vacuum pump 36.  When charged, the autoclave is sealed, and, if desired, heated. The pressure is then intermittently released, the vapours evolved being condensed and removed via pipe 38.  The mixture may be crystallized by cooling, and dried by heating under reduced pressure. The material is then conveyed to a hopper 41, and thence it may be passed to grinding apparatus 48, and discharged by a conduit 49; alternatively it may be treated, preferably under reduced pressure, with gaseous, anhydrous or aqueous ammonia in a tank 45, then ground and <PICT:0357508/III/1> discharged; or it may be ground prior to the ammonia treatment. The autoclave product may be mixed with an inert substance such as sawdust prior to ammonification.ALSO:A phosphatic fertilizer, obtained by a process comprising the mixing of a stream of acid with a stream of finely divided phosphatic material and allowing the acid and phosphate to interact under pressure, is treated after drying, preferably under reduced pressure, with gaseous, anhydrous or aqueous ammonia, then ground and discharged. Alternatively, it may be ground prior to the ammonia treatment.  The autoclave product may be mixed with an inert substance such as sawdust prior to ammonification.

Title: Improved control-systems for aircraft
IPC: F02D29/00
Filed: 1939-04-11
Abstract: 528,249. Controlling aircraft. BRISTOL AEROPLANE CO., Ltd., and MAYER, F. April 11, 1939, No. 11008. [Class 4] A control system for aircraft comprises a main control operated by the pilot and an auxiliary control or trimmer of less effect than the main control and operated by an engineer at a point from the main control to modify or adjust an approximate setting made by the pilot. The invention may be applied to throttle control for synchronizing engines, the control of airscrew pitch, adjustment of engine speed maintained by constant-speed mechanism, mixture strength, or engine temperatures, or for the control of ailerons, rudders, wing flaps &c. In the form shown, a plunger 24 operated by the pilot forces oil along a pipe 22 to operate a plunger 15 adopted to actuate a throttle control 10. Adjustment is made by a plunger 37 operated by the engineer to force liquid into a branch 35 in the pipe 22. Before the handwheel 42 operating the plunger 37 can be turned, a rod 47 normally locking the spokes of the wheel is depressed, and a longitudinally perforated plunger 45 interrupts the pipe 22 between the plunger 24 operated by the pilot and the auxiliary plunger 37. The auxiliary plunger may be operated by a lever, or it may be replaced by a diaphragm. In a modification, the plungers 24, 15 are replaced by doubleacting pistons in cylinders connected at their upper and lower ends by pipes across which is arranged a pair of trimmer plungers or a pair of diaphragms 'for making adjustments to the approximate setting of a control made by the pilot.

Title: Method and apparatus for seismic processing
IPC: G01V1/24
Filed: 1972-03-09
Abstract: 1377812 Seismic signal processing PETTYRAY GEOPHYSICAL Inc 9 March 1972 [10 March 1971] 11018/72 Heading H4D  Common depth point, seismic traces are processed by a method comprising the steps of (a) establishing a range of acceptable seismic interval velocities for reflection events on the traces, as a function of trace time, (b) picking trace events, (c) detecting and storing the average velocity and occurrence time of the first event which yields an interval velocity falling within the established range, (d) detecting and storing the average velocity and occurrence time of the next event which yields an interval velocity within the established range, and (e) repeating step d sequentially for succeeding events. In the Fig. 3 embodiment static and optional initial (assumed) normal movement (NMO) or other corrections are applied at 302 to a field record of common depth point (CDP) traces. The corrected traces at 304 are grouped in "files" according to depth point and significant reflection events are picked at 305 by known methods (details given) and are identified by discrete values which could be plotted as "dots" at the appropriate trace times. Values of the amplitudes, reflection times and dominant frequencies of these events may be stored and used as additional criteria for event picking. From misalignments of the dots of a trace file, residual NMO corrections are determined and, when added at 307 to the initial corrections give the actual NMO corrections needed for that file. Comparing these actual NMO values with a table of NMO values associated with given average velocities and source-detector offsets enables the event velocities to be determined. By multiplying the average velocity associated with an event by the one-way travel time associated with that event at 311 a value of "stacking depth" is derived. The stacking depth values for various events are plotted at 312 by a pen- or cathode-ray tube-recorder as a function of two-way travel time and enable primary reflections to be identified. At 134 a first event is identified as being a primary reflection if its average velocity is within prescribed limits. A second event is identified as a primary reflection if the interval velocity associated with both it and the first event is within prescribed limits, and so on. A series of interval velocities is thus computed at 314 and if they are within preset tolerances of predetermined nominal values they are used to derive a smooth stacking depth/ two-way time curve at 315. From this curve refined values of the actual NMO are computed at 316 then compared with the initial NMO values at 317 to determine residual NMO corrections which are applied at 318 to the trace file from 304 or 306. The corrected traces are then stacked at 319, e.g. by counting coincidences of dots in the traces from 306. The refined values of NMO may be used to update the initial values at 303, and the curve 315 may be used to update the interval velocity nominal values at 313.

Abstract: 1378432 Linkwork; controlling hydraulic variable-ratio gears AIR-LOG Ltd and S TIMMINS 9 Feb 1973 [10 March 1972] 11364/72 Headings F2K and F2D In an hydrostatic transmission, for an earth moving vehicle or a transport and/or loading vehicle (for example for loading aircraft) including a diesel engine driven variable displacement swash-plate pump driving a fixed or variable displacement motor, a pump displacement pushpull control rod 16 is actuated in accordance with engine throttle pedal push rod 13 and a driven operated road speed selector control push-pull rod 12. The throttle pedal rod 13 is connected to an arcuate "T"-shaped lever 1 fulcrumed at 2 and spring biased at 7 against a stop 8, an arm 6 of the lever 1 being connected at 15 to the engine throttle control. The lever 1 has an arcuate slot 11 in which a slide member 3 is movable by the road speed selector control rod 12 via a bellcrank 4 and pivotally connected link 5, the slide member 3 being connected to the pump displacement control rod 16 by a bellcrank 10 and pivotally connected link 9. The arc radius of the slot 11 and length of link 9 are equal. The arrangement is such that when the vehicle is at rest the slide member 3 is maintained at fulcrum point 2 via the speed selector control to set the pump displacement at zero to provide a neutral position whereby the engine throttle may be operated without actuating the hydrostatic transmission so that other hydraulic systems on the vehicle may be driven by the engine while the vehicle is stationary. The bellcrank 10 is arranged so that when in the position shown in Fig. 1, the pump displacement is set at zero. Clockwise or anti-clockwise turning movement of the bellcrank 10 (Figs. 2 and 3, not shown) from this position will angularly adjust the pump swash plate to effect forward or reverse drive respectively. The linkage arrangement is such that the angle of the pump swash plate increases as the engine speed is increased such that when the engine is running at low speeds and hence low torque, the angle of the swash plate and hence displacement of the pump is also kept low. When the hydraulic motor is of variable displacement, the speed selector may also be connected by additional means to the motor so that when the speed selector is moved in a direction to increase the vehicle speed the displacement of the motor is reduced.

Abstract: 109,049. Donkers, L. B. Aug. 19, 1916, [Convention date]. Sweeping-machines; taking-up mud and d refuse for removal.- Relates to machines for sweeping refuse on roads and collecting the sweepings, of the kind in which an obliquely-mounted cylindrical brush actuated from the back axle of a four-wheeled carriage, and capable of being raised and lowered, delivers the sweepings to a scoop or collector flap from which they are taken by an elevator at the side and delivered over a pivoted flap into a tipping tank or receptacle, and consists principally in the adaptation thereto of water-sprinkling arrangements and of a screw elevator. The brush may be made in segments fitting into circular grooves in the flat end plates, and, when partly worn, the segments may be moved to grooves of larger diameter to restore the brush to its original size. In the form shown in Fig. 1, the brush 12 sweeps refuse, previously sprinkled with water from a pipe 47, over the flap 23 into the bottom of an inclined tube 25. An elevating-screw 27 rotating within the tube 25 delivers the refuse through a shoot 37 into a bin 4. The bin, when filled, is tipped by rotating handles 45 at each end of a transverse shaft 44, thereby, through chains 42, rotating screws 38 working in nuts 39 swivelling on each side of the bin. The shoot 37 is pivoted so as not to obstruct the tipping of the bin. Near the driver's seat 13 are arranged (1) a lever 14 for raising the brush and (2) a wheel 21 for operating clutches situated near each wheel on the rear axle 7 so as to permit one wheel to drive the brush and the other to drive the elevator screw 27. Fig. 4 shows a rotary brush made in segments 49 which, when the brush is new, fit into circular grooves 51 in the end plates 52. When half worn, the segments may be moved into grooves 54 of larger diameter so as to restore the brush to its original size by using double the original number of segments.
